I have recently started my business & have to make my first VAT return (April, may, june).  Many of my purchase invoices go back as far as nov, dec 2014.  But my business start date is 01/04/15.

If I use Nov 14 periods onwards will the purchase vat roll forward to the June 15 return?

I did think about entering all the older invoices into the march period but I think this would be incorrect?
